To ctZZ whom, ii may concern.-

Be it known that I, ISAAC l/V. DAY, a citizen of the United States, anda resident of Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inVVater-Closets, of which the following is a specification.

My invention relates to water-closets; and it consists in certaindetails of construction, to

ro be more fully set forth in the following specifcation.

To enable others to understand my invention, reference is had to theaccompanying drawings, in which- Figure l represents a broken view of awater-closet bowl, supportingbase therefor, clamps for coupling the footof the bowl to the base, section of the floor on which saidbase rests,broken section of the lead bend or 2o soil-pipe, and back air connectionprojecting from said base. Fig. 2 is a central broken sectional Viewofthe bowl, sectional view of a shortsupporting-basewithoutthebackairconnection and one of the clamps, and sectional view of thesoil-pipe and floor. Fig. 3is an upper plan view of the clamps and baseand section of the bowl through line ct a of Fig. l. Fig. 4 is a brokensectional View of one side of the bowl and sectional view of one side ofthe base. Fig. 5 is a detail side elevation of the filling-piece adaptedto be placed between the ears of the Vclamp to complete the circle ofsaid clamp. Fig. 6 is a detail plan view of the filling-piece. Fig. 7 isa detail cross-sec- 3 5 tion of one of the side clamps without thelining. Fig. 8 is a view similar t0 Fig. 7, showing the lining in saidclamp. Fig. 9 is an enlarged broken view of one side of the bowl andbase with one of the side clamps in position. Fig. lO is a detail brokenview, partly in section, of one of the side clamps, showing the seat forthe filling-piece. Fig. l1 is a detail perspective View of one of thepackingpieces for the filling pieces or blocks. Heretofore it has beenthe custom in the construction of water-closets to set the foot of thebowl on the floor and secure it thereto by means of screws passingthrough the fiange of said foot, rst placing putty or other like cementbetween said foot and floor. The un- 5o evenness of the iioor and flangeof the foot of the bowl made it difficult to screw the foot as firm asit ought to be, owing to the brittle nature of the porcelain of whichthe bowl is made. Consequentlyin the majority of cases the bowl restedvery insecurely and loosely on the cement. The usual shrinking of theioor would soon destroy the cement, so that in a very short time waterwould leak out between the foot of the bowl and floor, and as a matterof course this would also permit the escape of sewer-gas. To overcomethis trouble, I have first constructed a short straight tubular metallicbase adapted to be firmly secured to the floor; second, I have soconstructed the foot of the bowl that it will be supported on the topsurface of Said base. A pair of side clamps are caused to embrace theflanges of the foot of the bowl and projecting lip of the base, and asthese clamps are of a 7o semicircular construction they will not fullyembrace the circular construction of these parts. Therefore I haveprovided fillingpieces either of a U or V shape construction similar tothe shape of the said clamps in cross-section, which filling-pieces areplaced between the ears of said clamps and like said clamps embrace thelips of the base and foot of the bowl, thereby fully completing thecircle, and thus effectually preventing leakage 8o between the meetingfaces of the foot of the porcelain bowl and metallic base.

The construction and operation of my invention are as follows: I

l represents the bowl, which may be of any construction desired. 1L isthe foot of said bowl, having a ange portion whose exterior lb isbeveled for the purpose to be hereinafter more fully explained.

2 is the metallic base, consisting of a short straight tubular portionsimilar to a short section of piping and having the flange 2a, adaptedto rest on the door 3 and to be firmly secured thereto by means of thescrews 4. The

interior of said base (see Fig. 2) is provided with the inclinedinwardly-projecting lip 2", to which is secured the soil-pipe 5 by meansof solder 6. The upper portion of this base has the iiange 2, having theouter inclined face 2d to conform to the angular construction ofthe footof the bowl. It also has the inwardly-projecting lip 2e to give agreater bearing-surface for the foot of the bowl. The upper surface ofthis base is provided with the corrugations 2f to more readily hold thepacking-ring 7 in place.

8 and 9 are the side clamps, each of which is provided with the ears 10and 11, having holesl therethrough for the bolts 12. These clamps, Fig.7, have an interior U or V shape surface adapted to conform to andembrace the flanges of the bowl and base.

13, Fig. 8, is a lead lining or other non-porous material adapted toreadily conform to the interior surface of the clamps. It will beobserved that a portion of the interior surface of these clamps isenlarged so as to form the shoulders 8a for the purpose of moreeffectually retaining the lining in place. When,

therefore, the lining is inserted, the inner sur-l face of the clampswill be a straight incline, so as to conform to the inclined surface lband 2ll of the porcelain bowl and metal base, so that when the clampsare screwed up the pressure will by reason of these inclined surfacestend to draw the foot of the bowl firmly against the flange of the base,and, bearing as they do on nearly the whole of the exterior surface ofthe foot of the bowl, there is no tendency to fracture the porcelain, aswhen the same is screwed to the door, as heretofore. Besides, thepressure of these clamps being inward toward the center of the bowl,there is no possible chance of the bowl shifting on its metallicsupport. It will be observed (see Figs. 2 and 9) that the bottoms of theU or V shape mouth of the clamps are made deep enough so that the apexwill never come in contactwith the edges of the foot of the bowl oriiange of the base, so that all the pressure applied to the clampsisexerted against the beforementioned inclined sides. As the clampsadapted to embrace the foot. of the bowl and upper liange of the basemust necessarily be of a semicircular construction and the said foot andbase are liable to vary in size, it would be impossible to bring theears of such clamps together and always be sure of exerting the requiredpressure, and thus maintain the bowl tirmly on the base and also preventpossible leakage between their meeting faces. To complete the circle, Iemploy two filling-pieces 14 and 15, Fig. 3, one between each pair ofears. These filling -pieces are of course constructed exactly alike and(see also Fig. 5) have an angular mouthsimilar to that described for theclamps, and are adapted thereby to embrace the inclined faces of thefoot of the bowl and upper flange of the base, each being provided withthe lead lining 16. While'these filling-pieces are short, still they aremade to conform to the same circular construction as theclamps. To holdthese filling-pieces in place firmly against the flanges of the bowl andbase, I have provided the recesses 17 in each ear of the clamps. Theinternal walls of these recesses conform to the outer shape orconfiguration of the filling pieces or blocks. p It will be observed(see Fig.V 6) that the sides of these filling-pieces are tapered toconform to the side walls 17, Fig. 10, of the recess, so that when theclamps are drawn together the side pressure will have a tendency tocrowd the filling-piece against the before-mentioned flanges. The leadlining 1S covers the said side walls 17 and end walls 17h. In fact,thelining is shown as covering all of the interior walls of the recesses;but it is not absolutely necessary, except that the severalbearing-surfaces are not apt to be so closely fitted but what a leakmight occur, and the lead lining will more readily conform to anyunevenness. When the side clamps are firmly brought together, theyshould also exert a pressure against the 'end walls of thefilling-pieces as well, in order to insure a perfectly tight joint. If,therefore, the filling-pieces are not pinched firmly, lead or any othernon-porous but compressible packing is placed between the ends of thefilling-piece and the end wall 17LL of the recess in the ears of theclamps. 18, Figs'. 1, 3, and 1l, show such packing. By this arrangementevery part of the circular construction of the foot of the bowl andiiange .portion of the base is fully covered, so that every avenue ofescape for the water or gases is closed. In the event of having toinspect or repair the trap at any time all that is necessary is simplyto disconnect the clamps and remove the bowl.

18h, Fig. 1, is a back air connection integral with the base 2. Toprovide for this, the base will have to be made deeper when a back airconnection is desired than shown at Fig.` 2. In such casesthe base shownat Fig. 1 is used; otherwise the base shown at Fig. 2 may be employed.

The advantage to be derived from the abovedescribed construction isapparent to both the plumber and user. In the first place, the plumbercan make a better joint, as he has no fear of breaking the porcelainbowl, as when it had to be screwed firmly to the floor, in order to makea common putty, cement, or rubber-gasket joint, and the user isbeneiited in having a tight closet.

It will be understood that while Imake use of the word bowl7 and show aplain bowl, either porcelain or metal, provided with a foot adapted torest on a separate base, it also applies to a combined bowl and trap. Infact, my invention is adapted to be applied to any form or constructionof closetbowls, either porcelain or metal, as it is intended to do awaywith the necessity of tryloo` ing to make a'tight connection with thelead bend or soil-pipe at the floor or side wall, but instead to makesuch connection to prevent the escape of water or gas away from the saidioor or side wall.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A bowl provided with an outwardly-cxtending flange upon its loweredge, a base provided with an outwardly-extending flange upon its upperedge, and an inwardly-extending flange upon its lower edge, and suitableclamps for connecting the base and the bowl, combined with a soil-pipewhich extends into the base, and which has its upper edge expandedoutwardly so as to catch over the inwardly-extending flange upon thebottom of the base, substantially as described.

2. The herein-described improvement in water-closets, consisting, incombination with a metal base adapted to support the bowl of a closet,said base and the foot of said bowl having flanges with correspondinglytapered or inclined surfaces, of semicircular side clamps adapted toembrace said flanges but not to meet each other, lling-pieces adapted tobe placed between said clamps and also adapted to embrace such portionof said flanges not embraced by said clamps, recesses being provided inthe ears of said clamps for said filling-pieces, for the purpose setforth.

3. In a water-closet of the class described, the combination of a shortmetal tubular supporting-base externally flanged at top and bottom andinternally flanged at its bottom, an

independent soilpipe removably secured therein above said internalflange, and a bowl portion removably clamped thereon, the outlet of bowland inlet of soil-pipe arranged in alinement with each other and withthe tubular base and the upper end of the soil-pipe terminating at theinterior wall of said tubular base, substantially as described.

4. In a water-closet of the class described, the combination of a shortmetal tubularsupporting-base externally lianged at top and bottom andinternally flanged at its bottom, a soil-pipe detachably secured thereinabove said internal flange, a trap-bowl portion flanged at the bottomand supported on the upper flange of the tubular base in alinement withthe axis of the base and soil-pipe, and semicircular clamps removablysecuring the base and bowl together, substantially as described.

5. The combination with a water-closet bowl having an outwardlyextendingflatfaced llange at its lower end, of a tubular metallic supporttherefor having a horizontallyextended upper seat for the flange of thebowl and an internal annular flange to support a flanged upper end of asoil-pipe, and means for clamping the bowl and support together.
